Fabrication of silver–tetracyanoquinodimethane nanorods arrays for field emission application

Morphology tailored AgTCNQ (Silver-7,7,8,8-tetracyanoquinodimethane) nanorod arrays were grown on large-area flexible carbon cloth substrate via organic vapor transport reaction under different reaction conditions. The morphology and crystal structure of the synthesized samples were characterized by FESEM, HRTEM and XRD, respectively. The field assisted electron emission properties of the nanostructures were investigated. The turn-on and threshold field values of the optimized AgTCNQ nanorods are 2.85 V/μm and 6.43 V/μm respectively. The results revealed that the charge transfer (CT) complex of nanostructured AgTCNQ is the potential candidate for cold cathode emission applications.
